Accurate prediction of refractive index of inorganic oxides by chemical formula

Predicting refractive indices of the borate optical crystals

“…From Table 1 and previously calculated results [10], it shows that the relative errors between our calculated refractive indices and the measured values are within 3.5% in all the cases and in all directions, which are much better than the values obtained from both ab initio and empirical methods previously proposed [1,2,8,9]. It can also be found that most of the calculated absolute refractive indices agree with the experimental ones in the 1% margin with some exceptions: CsB 3 O 5 , CsLiB 6 O 10 and LiKB 4 O 7 .…”

“…More recently, Korotkov and Atuchin [9] reported their prediction of the mean refractive indices based on electronic polarizabilities of ions and ionic radii in crystals and the relative errors are 0-15%. However, crystal anisotropy was not considered in both works and therefore those calculations only gave the mean refractive indices.…”

Preparation and structural properties of nonlinear optical borates K2(1−x)Rb2xAl2B2O7, 0<x<0.75

“…It should be pointed, that wide range tuning of the structural parameters is possible in solid solutions K 2(1−x) E 2x Al 2 B 2 O 7 (E = Na, Rb). This gives a promise for a wide range tuning of linear optical parameters of the crystals because ionic refractions of Na + , K + and Rb + ions are noticeably different [29,30].…”

Growth, Structure and Spectroscopic Characterization of Nd3+-Doped KBaGd(WO4)3 Crystal with a Disordered Structure

“…where I q ( λ ) is the emission intensity at wavelength λ with q polarization, A q is the emission probability which can be calculated from the Judd-Ofelt theory [21] , [22] , the refractive index n is calculated to be 1.83 using the method mentioned in Ref. [23] .…”
